To all @07mm t may concern:

Beit known that l, CHRISTIAN CHRIS- 'rnNsnma citizen of Germany, residing at Rye, in the county oflestchester and State of New York, have invented certain. new and useful improvements in Methods of and Means for Laying Out Blanks o-f Flaited Articles, ofvwhich'the following is ar specification. i y

This'invention relates .to certain new and useful vimprovements in methods of y and means for lay/ing out blanks of plaited articles, particularly valances of window draperies and thelike. y

An object of the invention is to furnish a simple and accurate method for laying .out 'the blanks of a plaited article of known form and dimensionwhereby Valances or the like may be cheaply and ,easily'conf stru'cted with thel requirement of no especially skilled labor. y p

Another object of the invention is to provide means for enabling an unskilled person to lay outthe blank of a lplaited article, such as a valance, the invention providing means for denoting the required length or? depth ofthe plaited article and simultaneously denoting thev required edge and depth dimension of' theblank necessaryto construct the plaite'd article of said predetermined depth. l

wWith the above general objects in view and others that will appear as the nature ofV the invention is better understood, the same consists of the novel` form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and'claimed.

In the drawings, wherein like reference characters designate corresponding parts throughout the several views,

Figure l is a front elevational view of a chart or means for laying out blanks of plaitedY articles constructed in accordance with the present invention and illustratingthe method constituting part of the present invention,"V 1

Referring 4particularly to Fig. l, the

methodv of laying/out the blanks vof a cal base line 5 and a horizontal base line'. `6, laying off on the vertical base line, as at 7 and 8 respectively the points for the article depth and the blank depth, arepre-A sentation, as at 9of the plaited article being provided upon thechart sheet lOybe- A tween the point 7 and the horizontal lbase line 6, and the vertical base line 5 being. disposed at the vertical center ofthe plaitedarticle when both vertical halfl sections of said article are similar, as shown..V f

yThe top width of the blank is next laid out on the horizontal base line by means of vertical sub-base lines 11 which intersect the horizontal base line 6 at the top' of the blank at the points ll. The extreme'width points for 'the blank are then laid off at opposite sides of the vertical base line 5 as at 12, preferably by means of further subbase lines which are vertically arranged as at 13 at right angles to the horizontal base line 6, Av horizontal bottom width line for the blank is thenl drawn in the desired direction or directions vfromfthe point 8 as plaited article consists in drawing a vertii at 1 4. The sideedge lines. of the blank are then drawn' from the ends of the top and bottom width lines of the blank'to! the eX- treme width point l2 of the blank as at 1.5, and then the width of'theplaits is laid off along the edge line or lines ofthe blankwhere theV plaits are to.; be folded vand se-` cured, as at 16,. This may be done by inwidthof the blankLbet-w'een each sub-base line 11' and the 'adjacent sub-base line '13 whereby the width of the blank is shown for thevspacebetween theextreme width pointsof the blank andthe top width points of the blank. The method of laying out the blank has been described with respect to the pattern or chart sheet from.which the measurements and outlines are taken to be drawn upon .the fabric from which in the same manner as the fabric, the der' the plaited article is to be formed', but as the pattern or chart'sheet willbe laid out scription in connection with the chart sheet rather than the fabric willbe clear.

In case the top edge 'of thearticle 9- Vis desired'to be droopedslightly, a curved lineV maybe drawn as at 2O to denote the same and as shown. in Fig. 1, the greatest dis'- tance of sag may be indicated in inches as will also be the case with respect to the length of the bottom width line 1eer The lines 11 will be suiliciently spaced apart. a

greater distance than the topwidthorpv the plaited article to allow for this sagging.y

The chart sheet 10 is provided with a plurality of pairs of substantially vertical slits as at 21 whereby a plurality of rearwardly directed slide. retaining loops are formed :tor the rece ation of horizontal slide scales 22 and 23., tliefslits kbeing provided inthe proper places so that when the loops are depressed rearwardly exposure openings Vfor the numerals on the Ascale strips are formed adjacent the top width indicating line 17, depth line 18, width lines 19' and vertical base line 5 as well asthe upper edge lines 15. i

llt will beV noticed that when the plaited article 9 is plaited uniformly at each side ol' the vertical base line 5, the upper side edge line 15 will be of' the same length as the depth line 18'01" the plaited article, although terminating above the point 7 because of the, line 15 being at an inclination.

It will also, be noticed that the depth of the blank will always'bear a predetermined relation to the'depth of the plaited article.,

and that the distance of projection of the blank Vbetween the ends of the topV width line of the blank and the extreme width portion oli'the blank as denoted Vby .the length of the lines, 19 will also bear a predeter- Vmined relation with the depth oi the plaited article, and for this reason the plurality or' slide scales or stripsIv 22 may be rigidly con.- nected at the ends by a binding 24 and thus all be mowed simultaneously for exposing` a single numeral through each of theeXposui-e openings with the exception of the width indications olthe top of the blank, the scales being marked in proper predetermined relation for this purpose as seen clearly in Fig. 2. Thus, by positioning the multiple scale member comprising the boundY strips 22 so as to expose the numerals represent` ing in inches the depth of the required plaited article, the remaining dimensions will be exposed through the proper exposure openings, so that the depth of the blank and the like will be immediately indi cated; Asthe top width line .of the blank may be indelinitely varied withoutchangingV the remaining dimensions for increasing the width or the resultant plaited article, the

tabs may be provided at both ends ot the strip 23' as at 25 toY be conveniently grasped Vfor adjusting` the scale strips so as to expose the desired dimensions through the openings oi the sheet 10, ythe relative positions of the desired numerals upon the scale strip be'- ing of a predetermined varrangement Y as shown clearly in Fig.` 2.v

The invention may be employed for" laying out draperiesogt many different forms other than that described with respect to Fig. 1, and an example of one of these remaining forms is shown in Fig. 3 wherein the sheet 10 lhas the'horizontal base line 6 and vertical base line 5 with the representation 9 ,of the plaited article extending to either side of the line 5 and its-point ot depth indicated as at 7" on the vertical base line 5. VThe depth point 8" of they blank vis also denoted as in Fig. 1 and this isr also true yof the extreme Width line or points Vof the blank as at 12 assuming that the article is to be plaited uniformly at opposite sides ol. the vertical center or base line 5. As previ:

ously described, the edge lines ofthe blank Y are drawn in straight lines romthe ends ot the width line 111A and the ends oi the top width line or points .112L to the extreme width points 12. ln this .view the verticalV subbase lines 11b are provided in parallel relation at opposite sidesV ofthe vertical center or base line 5 to denote the top width line or lengthoii the blank at its top while Vthe i' distance between' saidv lines 11b and the eX-V treme width points 12y are denoted' by rthe exposure of measurement numerals adjacent the measurement indicating lines 19 similar measurement line 18 is provided lor the depth of the article 9 and the sagging of the drapery or article 9 is denoted `by the curved top line 2O as in Figi.V As

the drapery is to be eXtendedto a greater distance at one side of the vertical base line 5 than at theother to provide theextension -'a-, it' is necessary tol 'enlarge the blank and 2S. The extension of the edge 16 of Vthe blank consists of a line 3l drawn in zig zag fashion from the point 12 at this side of the blank toj the point 29 and gaged by a straight line 27 connecting said points, while the adjacent edge line 30 of the blank is determined by drawing a straightline lll) the invention the plurality offscale strips or slides 22 are exposed through suitable Vvopenings provided by slitting the sheet 10 substantially vertically as at 21 whereby the guide loops 32 for said scale strips` are formed. The scale strips 22 are connected toslid'e together by means of the end bindings or tabs 211 'and this may bedone by properly arranging the measurement numerals upon the strip 22 ina predetermined relation in'view of the fact that the measurements between the lines 13 and 28 and between the points 12 and 29 bearv a predeterminedrrelation to the other measurements with the exception of the top width line eX- tending from the lett hand point 11- to the right hand point 11a. rlhe length of this top width line or" the blank may be denoted by the exposure of a numeral on the separate slide strip or scale 23 through an opening` provided b-y slitting the blank as aforementioned, the measurement indicating line being provided at 17 adjacent this opening and the scale strip 23 being provided with end tabs 25. From the above it will be seen that b-y setting the multiple scale device comprising the strips 22 and bindings 24 at the proper position so as to expose the depth indicating numeral ot the required kind adjacent the line 18 and the depth numeral for the blankV adjacent the vertical base line 5, the proper measurement numerals will be exposed for the remaining lines adjacent the measurement indicating lines 19', 17, 27, 26 and 16.
